Python code to check whether the given number is positive or negative or 0
In this tutorial, we will discuss the Python code to check whether the given number is positive or negative or 0
In this post, we are going to learn how to check whether the given number is positive or Negative or zero using 3 ways in Python language
The logic to check positive, negative or zero
- Check the condition if(num<0), then number is negative
- Check the condition if(num>0), then number is positive
- Check the condition if(num==0), then number is zero
Python code to check whether the given number is positive or negative or 0
Check whether the given number is positive or negative or 0- using standard method
Program 1
#Pyton program to check number is positive or negative or zero
num=234
if(num>0):
print("{0} is a positive number".format(num))
elif(num<0):
print("{0} is a negative number".format(num))
else:
print("you have entered zero")
When the above code is executed, it produces the following result
234 is a positive number
In this program,
- integer variables num is declared and initialized
- The given numbers are tested whether it is positive, negative or zero using if- elif statements
- Then,the program is displayed the output of using print() function
Check whether the given number is positive or negative or 0- using User input
Program 2
#Pyton program to check number is positive or negative or zero
num=int(input("Enter the number: "))
if(num>0):
print("{0} is a positive number".format(num))
elif(num<0):
print("{0} is a negative number".format(num))
else:
print("you have entered zero")
When the above code is executed, it produces the following result
Case 1
Enter the number: 124 124 is a positive number
Case 2
Enter the number: -765 -765 is a negative number
Case 3
Enter the number: 0 you have entered zero
Approach
- integer variable num is declared.
- The program asks input from the user
- Then the user enters the input values for num.
- The program will read the input using input stream and store to the variable num
- The given number is tested whether it is positive, negative or zero using if- else statements
- Then,the program is displayed the output of using print() function,
Check whether the given number is positive or negative or 0- using function
Program 3
#Pyton program to check number is positive or negative or zero
num=int(input("Enter the number: "))
def FindPositive():
if(num>0):
print("{0} is a positive number".format(num))
elif(num<0):
print("{0} is a negative number".format(num))
else:
print("you have entered zero")
#FindPositive();
When the above code is executed, it produces the following result
Case 1
Enter the number: 36 36 is a positive number
case 2
Enter the number: -75 -75 is a negative number
case 3
Enter the number: 0 you have entered zero
Approach
- integer variables num is declared.
- The program asks input from the user
- Then the user enters the input values for num.
- The program will read the input using input stream and store the variable num.
- Define the function findPositive(); to find whether the number is Negative or Positive or zero
- Call the function to produce output
- finally, the program displays the output using print().
